MOSES GREENSFELDER, OF BALTIMORE, MARYLAND.

ClGAR-BUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 384,757, dated June19,1888.

Application filed July 18 1887. Serial No. 244,590. (No model.)

To all whom it may concern.-

Be it known that I, Moses GREENSFELDER, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Oigar-Bunching Machines, of which thefollowing is a specification.

My invention relates to a cigar-making machine, and has particularreference to a ma chine for forming the bunch and filler and applyingthe wrapper thereto.

The invention consists in novel parts, combinations, and features ofconstruction, and is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of the machine, except the buuch'slide andtable, which arein section. Fig. 2 is a horizontal section of thebunch-slide and pusher. Fig. 3 shows two sectional views of thefeed-cylinders. Fig. 4 is a vertical longitudinal section of themachine. Fig. 5 is a plan or top view of one-half of the apron andrelated parts on line 5 5, Fig. 1. Fig. 6 is a rear side elevation ofthe machine. Fig. 7 is an elevation of the front end of the machine.Fig. Sis a. view of the eccentric and rod-hangers.

The machine is supported on a suitable table, A, and standards A on thetable sustain a hopper, B,which basin its bottom a feed-cylindcr, O, towhich an oscillating motion is imparted by a rack-bar, a, engaging witha pinion, b, mounted on the journal bof the cylinder. An endlessfeed-belt, D, is mounted on two rollers, c c, at the upper and loweredge of the hopper-bottom B, and one side of the belt travels above thebottom and one side below it. The scrap'tobacco which is put into thehopper rests on the said feed-belt,and is thereby carried down to thefeed-cylinder O, which has a cavity or opening, d, to receive thescraptobacco, which is to form a cigar bunch or filler. A gage-ejector,O, loosely occupies the cylinder-cavity d, and is provided with twoscrews, 6, (see Fig. 3,) which regulate the depth in the cavity to whichthe said ejector In the present instance the ejector C, it will beunderstood, acts by gravity-that is to say,when the feed-cylinder O isturned so that its cavity (2 opens upward, as in Fig. 4, the ejector Cwill drop into the cavity as far as The guide E is supported onastationary frame, F, and immediately below the said.

guide is an apron, G, which passes over two rollers, ff, mounted on thestationary frame F, and two rollers, g g, on a pivoted frame, H, at thefront of the machine. The apron is connected to a bar, I, by means ofclip a thereon,

which incloses and keeps the apron in position on the bar. The bar Ifits and moves in horizontal slots I in the two sides of the stationaryframe, and the bar I is moved backand forth in the slots and draws theapron G back and forth with it each way. Between the roller f on thestationary frame and the roller 9 on the pivoted frame the slack of theapron sags down to form the bight h, wherein the bunch or filler isreceived, rolled, and wrapped. 1

The charge-guide E is provided with a pusher, J, which consists of ablock or crosshead, 9', which fits loosely in the guide E, and

has two set-screws, is, one near each end,which enter at the back, andthe points of which projectthrough at the frontside of the block andpress against the back of a flexible bar, j, near its ends, saidflexible bar being connected at j with the block j. It will be seenthatby The 55,

turning the set-screws k the curved shape of one end ofa rod, t, theopposite end ofthis rod being connected to a lever, t", which isattached to a cam, N, the mechanism of which will be presentlyexplained.

As the. charge of scrap-tobacco is ejected from the guide E by thepusher J it will drop back of the apron.

. m, which are pivoted on a crossrod, n.

into the bight h of the apron by means of the reciprocating rod 2. Thisbight or loop is formed by collecting the aprouslack together betweenthe two rollers fand g, as shown in Fig. 4. A thin plate-spring,f (seeFig. 1,) is fastened at the under side of the discharge end of the guideE and bears down on the apron G directly over the roller f, and servesasa brake to prevent the apron from slipping back freely. At the propertime in the movements of the machine the said rollerf willbe partlyturned, so as to draw forward to the bight any slack that may be in thetop and To thus partly turn this rollerf, two upright arms, Z, arepivoted to the stationary frame at Z, and the said'two arms areconnected by a front curved bar, Z". One of the arms Z at one side has adownward projection, Z, to the end of which an operatingrod, Z, isattached. The upper end of each of said upright arms Z carries a flatspring, P, which projects forward and is in contact with the lower sideof the roller f.

It will now be seen, by reference to Figs. 1 and at, that when the topsends of the two arms Z move from right to left the flat springs Z will,by their frictional contact with the roller f, cause said roller topartly turn and thereby draw forward to the bight any slack that may bein the top of the apron.

The pivoted frame H comprises two levers, The upper ends of these leverscarry the rollers g g, and also carry above the upper roller a rest orsupport, 0, for the leaf or wrapper of the cigar. The person operatingthe machine will have position at the front end adjoining the saidleaf-rest 0, and a leaf of tobacco may first be laid on the rest, andthen the operator will slide the leaf back and down into the bight.

A fiat spring, is attached to the front curved bar, Z and projectsupward and bears against the apron G, as shown in Figs. 4 and 7, andpresses it hard in contact with the rollers g g, and serves as a braketo prevent the apron-slack which is in the bight from slipping forwardfreely.

The lower ends of the frame-levers m are connected by a crossbar, p, andan operatingrod, 12, is attached thereto.

The rack-bar a, which oscillates the feedcylinder, is moved by a lever,c,which is pivoted at a, to the table. A crank-wheel,g,is on the mainshaft L, and a link, q, connects the lower end of the said leverwith-the crankwheel. It will thus be readily understood how, by therevolution of the main shaft L, the rack-bar ahasaback and forwardmot-ion and the feed-cylinder is oscillated.

The feed-belt D is driven by a cord, 0 which passes over a pulley, 0 onthe upper feedbelt roller, 0, and thence down to a pulley, c, on themain shaft.

The rod 2', which operates the pusher J, is moved by a lever, i, whichis pivoted on a hanger, i",under the table. The main shaft L has aneccentric, r, and the lower end of said has a side groove, 8.

pusher-rod lever i is jointed to the arm r of the eccentric ring, asshown in Fig. 8.

The apron -bar I is' reciprocated in the frame-slots I by the followingmechanism: A cam, N, is mounted on the main shaft L and Alever, 1 has aslot,t, which fits loosely on the main shaft, and is provided witharoller on the pin t,and said roller occupies the cam-groove s. Arock-shaft, I is mounted in the hangers ti and a short arm, a, is keyedfast on the said rockshaft. At each end of the rock-shaft are longupwardprojecting arms I, (see Fig. 6,) Which vibrate as the rock-shaftmoves. These long arms I are jointed at t to arms 1; at each end of theapron-bar I. It will now be seen that when the cam N revolves theapron-bar I will reciprocate, and by drawing the apron back and forwardwill roll the filler in the bight h.

The rod Z*,which imparts a swinging movement to the two upright arms Zfor partly turning the roller f, is moved, and also the rod 1), whichgives motion to the pivoted frame H by an arm, 0, depending from ashaft, 19', in bearings under the table. The rod 1* is attached to saidarm 0 at one side and the rod p at the otherside. The shaft p from-whichthe arm 0 depends, has another arm, 1), provided with an ordinaryfrictionroller, which bears against the rim or peripheryp of the cam N.Thus the said cam has two effective or operating parts-the groove .9 andthe rim p Through the action of the camrimp, arm 0, and rodp' thelowerend of the pivoted frame H will be pushed in a direction away from thesaid cam N, while a spiral spring, 0:, attached to the table and lowerend of the pivoted frame, will draw the latter back again toward thecam.

The pusher J has its block j connected with the rod '5 by a hinge-joint,j This joint gives freedom to the pusher to turn with re spect to therod.
